(2003) The effect of pressure on the radiative efficiency of InAs based light emitting diodes. . physica status solidi (b), 235 (2). pp. 312-316.

The spontaneous emission of 3.3 mum light emitting diodes (LEDs) and lasers based on InAs alloys were studied as a function of hydrostatic pressure. An increase in light output with increasing pressure has been observed, with a general comparison of the performances of type I and type 11 structures given in terms of the radiative and non-radiative processes involved. The experimental results provide evidence that the so-called CHSH Auger process is insignificant in these devices. However, Auger recombination mechanisms are still shown to dominate the response of these type 11 LEDs in contrast to type I lasers where competing radiative processes appear more significant.
